How Long Does Lavender Live, and Why Does It Get Woody?
The lifespan of lavender plants in gardens and on farms, why lavender becomes woody, how pruning extends its life, and when to replace plants.
A well-pruned lavender plant typically lives and flowers well for 10–15 years in a garden; on commercial farms, fields are usually replanted every 8–12 years when yields fall. Plants that are never pruned often become woody, split and decline after just 4–6 years.
Why Lavender Becomes Woody
Lavender is a sub-shrub: each year's growth turns woody at the base. Leaves and flowers grow only on young shoots, and the plant rarely produces new buds from old, bare wood. Without pruning, the green part moves further out each year, leaving a bare centre.
How to Keep Lavender Young
- Prune every year after flowering, back by about a third.
- Start pruning in the first year to build a compact shape.
- Avoid fertilizer and rich soil, which cause fast, weak growth.
- Keep the base dry and well ventilated.
When to Replace
If a plant has split open with a large bare centre and only a few green tips, take cuttings and replace it.
